APPROVALS
All Viking Z SEVEN SCBA are CBRN certified and NIOSH
approved, meeting the NFPA 1981 Standard, 2007 Edition
and the NFPA 1982 Standard, 2007 Edition (when equipped
with PASS) requirements.
NIOSH/OSHA WARNINGS
The following warnings are given in accordance with accept-
ed safety conventions and/or NIOSH/OSHA requirements,
and apply to the use of breathing apparatus in general.
HEALTH LIMITATIONS: Wearers of the SCBA should be
certified medically fit prior to use. In addition, there are both
physiological and psychological limitations which should be
considered before using SCBA. They include, but are not lim-
ited to:
* Emphysema
* Chronic obstructive pulmonary disease
* Bronchial asthma
* X-ray evidence of pneumonia
* Evidence of reduced pulmonary function
* Coronary artery disease
* Severe or progressive hypertension
* Epilepsy (grand mal or petit mal)
* Pernicious anemia
* Diabetes (insipidus or mellitus)
* Breathing difficulties when wearing an SCBA
* Claustrophobia or anxiety when wearing an SCBA
* Abnormal EKG results from resting or stress tests
* Punctured or ruptured ear drum
WORKING TEMPERATURES: The VIKING SCBA is ap-
proved for respiratory protection during entry into or escape
from oxygen deficient atmospheres, gases, and vapors at
temperatures above -25°F. When used below freezing, care
must be exercised to prevent moisture from entering the de-
mand exhalation valve. The facemask should remain on the
docking hook when not in use. On the AirSwitch model, the
slide should be stored in the up position when not in use. For
the RDV demand valve, the RDV should be stored on the
docking station found on the waistbelt. This includes when
cylinders are being changed.
DURATION OF USE: Although the VIKING has been ap-
proved as either a 30-minute, 45-minute, or 60-minute breath-
ing apparatus, the wearer’s varying work rate, physical condi-
tion and other factors could substantially shorten the actual
usable duration of the unit.
SCBA LIMITATIONS: An SCBA can only protect the wear-
er’s respiratory system. Other protection may be necessary
to avoid contamination through skin absorption. If these types
of materials are suspected, an effective full-body covering of
impermeable material must be worn with the SCBA. A univer-
sal Level A HazMat suit is available for the VIKING SCBA
from HazMat suit manufacturers.
FACIAL HAIR: Facial hair or any other items which may in-
terfere with the facemask-to-face seal, including the nosecup,
or the operation of the exhalation valve, must not be allowed.
These include beards, sideburns, mustaches, bangs, head
coverings, or anything else that may interfere with the correct
seal of the facemask and/or nosecup to the face. See NFPA
1500 and ANSI Z88.2
EYE WEAR: Eye glasses shall not be used when the temple

2
bars interfere with the proper seal of the facemask to the
face. If a user must wear corrective lenses while wearing the
SCBA, they can be mounted in the facemask using a special
lens mounting kit (AVON-ISI p/n 136003) available from
AVON-ISI or through your local AVON-ISI authorized distribu-
tor.
MANUAL BYPASS: In compliance with NIOSH requirements,
the Viking SCBA has a manually operated bypass which pro-
vides a continuous flow of air to the facemask when required,
independent of normal operation of the regulator. The bypass
is opened by turning the red knob on the AirSwitch 90 de-
grees in the direction shown by the knob arrow. The RDV by-
pass opens by turning towards the user. Use of the bypass
will shorten the duration of the SCBA.

All Viking Z SEVEN SCBA are NIOSH CBRN agent approved,
NIOSH approved and NFPA 1981Standard, 2007 Edition
compliant. The Viking Z SEVEN features a heads-up display
(HUD) that monitors cylinder pressure and an emergency RIC
connector that is used to refill the air of a down fire fighter.
The Viking Z SEVEN model has VAS (Voice Amplification
System) and data logging as standard features. Additional
options of the Z SEVEN model include radio interface, voice
activated communications, integrated PASS, buddy breather
and airline. All Vikings are available with light weight carbon
cylinders in 30, 45 or 60 minute rated durations.
The AVON-ISI Viking Z SEVEN is a self-contained, open-cir-
cuit, compressed-air breathing apparatus, which is approved
by the National Institute of Occupational Safety and Health
(NIOSH) and certified compliant to
NFPA 1981Standard on
Open-Circuit Self-Contained Breathing Apparatus for Fire and
Emergency Service
,
2007
Edition.
Positive pressure inside
the facemask, both during inhalation and exhalation, ensures
that any leakage due to improper fit or component failure will
be an outward flow of air.
The Viking Z SEVEN SCBA consists of several major compo-
nents described in the following paragraphs.
1.1 FACEMASK
The AVON-ISI full facemask
assembly has a two point pull-
forward Nomex net harness
with an optically-corrected,
double curve high-impact
polycarbonate visor. The vi-
sor’s scratch-resistant coating
conforms to NFPA standards.
The interior of the visor has a
permanent anti-fog coating.
The facemask standard seal
is high-strength butyl blend
and has a patented blended
shape which fits the firefight-
er's helmet without readjust-
ment. A standard black inner-mask nosecup reduces dead-air
space and CO2 buildup. The facemask has CBRN labels af-
fixed at both lower corners of the visor.
An in-mask HUD is mounted to the inner-mask nosecup. The
mask display includes five LEDs: red = ¼ full, yellow = ½ full,
1st green = ¾ full, 2nd green = full, and the last elevated yel-
low = low battery indicator. The HUD indicates remaining cyl-
inder pressure and provides the primary end-of-service time
1.0 DESCRIPTION OF VIKING Z SEVEN SCBA
alarm. The HUD can also provide additional status indicators
depending upon the options ordered.
1.2 AIRSWITCH® REGULATOR
The patented AirSwitch second stage regulator is incorporat-
ed into the facemask and combines the demand and exhala-
tion valves to greatly reduce breathing resistance. This also
allows for a longer duration of cylinder use. A speech dia-
phragm provides excellent clarity and voice reproduction
while incorporating the exhalation valve.
The AirSwitch features a fresh air mode which allows users
to go from cylinder air to outside air by depressing the two
control slide tabs inward and then raising the slide upwards
fully. Push down for cylinder or supplied air. The AirSwitch
should stay open prior to donning and doffing of the VIKING
SCBA. The AirSwitch is made of high performance engi-
neered plastics and incorporates a true manual bypass con-
trol for emergency use.
Down for supplied airUp for ambient air
• This approval applies only when the device is supplied with
respirable breathing air through 6 to 300 feet of hose at air
pressures between 80 to 120 pounds per square inch gauge or
from self contained air supply.
NOTE: Viking CBRN SCBAs are not approved for supplied air
use in confirmed or potential CBRN environments.
• If the supplied air fails, open the cylinder valve, unplug supply air
and proceed to fresh air immediately.
• Use adequate skin protection when worn in gases and vapors
that poison by absorption (example: hydrocyanic-acid gas).

1.3 REMOVABLE DEMAND VALVE (RDV)
REGULATOR
The Viking RDV
regulator is a mask
mounted second stage
regulator with a 1/8th
turn positive locking
mechanism, which
secures into the
facemask. The RDV
facemask incorporates
a speech diaphragm
that provides excellent
speech clarity even
under heavy breathing.
The standard HUD is still inside the facemask with the
microphone. Docking the RDV on the facemask also aligns
the electronic connection in one simple step. After removing
the RDV from the facemask, it should be stored in the docking
station on the waistbelt strap to keep free of dirt and debris.
1.4 FIRST STAGE PRESSURE REDUCER
Air leaves the cylinder, pass-
es through a sintered bronze
filter in the handwheel elbow
assembly, and then contin-
ues on through a high pres-
sure flexible hose to the first-
stage pressure reducer
where it is reduced to ap-
proximately 125 psi. The re-
ducer is a simple piston type
that requires no adjustment
and incorporates an automat-
ic, self-seating pressure relief valve to protect the low-pres-
sure components downstream. It is made of high quality alu-
minum, and is securely mounted inside the backframe assem-
bly.
1.5 END-OF-SERVICE INDICATORS
The primary
End-of-Service
indica-
tor is incorporated into the HUD.
The display will flash a single red
LED at 23% to 27% of rated cylin-
der pressure per NIOSH require-
ments. The primary end-of-service
alarm meets NFPA 1981, 2007
Edition requirements.
The secondary
End-of-Service
indicator is a bell mounted in-
side the backframe which is set
to activate at 23-27% of rated
cylinder pressure per NIOSH
and NFPA requirements.
1.6 BACKFRAME AND HARNESS
The backframe and harness assembly utilize ergonomic de-
sign principles to produce a com-
fortable, low profile unit that evenly
distributes the SCBA weight be-
tween the wearer’s hips and shoul-
ders.
The unique double-wall backframe
of the Viking protects major airlines,
the first stage reducer, bell alarm
and digital components. A quick-re-
lease cylinder band fits a wide
range of cylinders with an infinitely
adjustable latch to ensure a tight fit-
ting cylinder.
The harness material is NFPA com-
pliant, custom woven KEVLAR®.
The upper harness has very resilient foam rubber padding for
added comfort and PBI/KEVLAR cover for maximum durabili-
ty and protection. There is an optional backframe plate that
can be ordered (p/n 099038) to reinforce the upper harness
straps for departments that do heavy simulation training of
fire fighter rescue operations. A lower lumbar pad is standard
for added comfort and support.
1.7 CONTROL CONSOLE
The control console and PASS assembly communicate with
each other through a wireless
network. The network uses a dis-
creet frequency that eliminates
noise and resistance to other ra-
dio frequencies. This wireless
network joins the Control Con-
sole and PASS assembly to-
gether, allowing for constant data
to be exchanged. The PASS mo-
tion sensor on the Z SEVEN is in
the Control Console. When mo-
tion is detected, the PASS will re-
set for 25 seconds.
NOTE: Only Duracell MN 1500 or Energizer E91 1.5 volt AA
batteries are to be used with the battery packs. Be
sure to place batteries in the direction as indicated
on the battery compartment in order to prolong bat-
tery and fuse life. Use of other batteries will void the
intrinsic safety approval.

1.7.1 SERVICING CYLINDER VALVE
After each use, and prior to recharging, the cylinder valve must
be inspected for damage. If a new valve is replacing a valve
that was damaged in use, it will be necessary to hydrotest the
cylinder before installing the new valve.
NOTE: Any maintenance on the valve that requires
disassembly should be conducted by an AVON-ISI
Authorized personnel or an AVON-ISI technician who
is well trained in the hazards of high pressure
equipment. Never attempt to remove the valve from
the cylinder while there is any pressure in the
cylinder. Open the valve completely to be sure it is
empty. If the gauge shows pressure but you think the
cylinder is empty, contact the AVON-ISI factory for
advice by calling 888-474-7233.
NOTE: Prior to revalving a cylinder, you must perform the
following inspection:
• Remove o-ring from sealing threads on cylinder
valve.
• Clean threads to remove any lubricant.
• Inspect the cylinder threads, ensuring the threads
are not distorted or cracked.
• Inspect the valve threads, ensuring the threads are
not distorted or cracked.
• Install new o-ring.
If any threads are distorted or cracked, the parts should
be tagged “Out of Service” and be condemned.
1.8 CYLINDER AND VALVE ASSEMBLY
A range of cylinder types and capacities are available on the
VIKING 2216 psi and 4500 psi models. (Please see the table
in Section 1.10 for specifics.)
The cylinder valve is of aluminum construction with a
permanent teflon coating. The valve outlet is a standard
CGA-346 fitting on 2216 psi cylinders, and a standard CGA-
347 fitting on 4500 psi cylinders. Each valve has a dual-
reading pressure gauge. Valve protection is provided by an
elastomeric bumper. See section 2.3.2 for inspection prior to
use.
The valve can be used with AVON- ISI cylinder assemblies
between 23 cubic feet and 87 cubic feel. The cylinder valve
has a burst disc type safety device to protect the cylinder
from over pressurization.
The cylinders and valve are matched according to pressure.
The maximum pressure on the gauge built into the cylinder
valve should match the pressure rating on the cylinder. A
2216 psi valve will not fit into a 4500 psi cylinder and vice
versa. For easy recognition AVON- ISI has made 4500 psi
handwheels red and a 2216 psi handwheel black. (Exception:
Every Viking Z SEVEN has a RIC fitting attached near the
handwheel that allows a downed fire fighter to have their
cylinder charged from an outside source. NFPA 1981, 2007
Edition requires this fitting on all SCBA’s manufactured for fire
fighters. The RIC fitting is compatible with other
manufacturers and is intended as an emergency refill only.
The RIC fitting will not work as a transfill system between two
SCBA’s. There is a dust cap cover for the fitting to prevent
debris on the fitting. See section 4.7 for detailed working
instructions.
1.10 Mounting SCBA
If you mount the Viking Z Seven in a jump seat or mounting
system of any vehicle, you must ensure that the mounting de-
vice meets NFPA standards and that the mounting device
does not interfere with components such as cylinder, that
could cause damage or cause sudden loss of cylinder pres-
sure.
all Viking ST models will have black handwheels no matter
what the pressure rating of the cylinder.)
The cylinder valve has two sets of male threads - one will
screw into the cylinder and the other is used to attach to the
pneumatics of the SCBA. The latter threads are referred to as
CGA (Compressed Gas Association) threads. It is important to
protect the CGA threads so that the pneumatics will always
screw onto them without doing damage to the handwheel on
the pneumatics.
If any threads are distorted or cracked, the parts should
be tagged “Out of Service” and be condemned.
HANDLING PRECAUTIONS:
NEVER LIFT OR CARRY UNIT BY THE HIGH PRESSURE
HOSES. IF A HIGH PRESSURE HOSE BECOMES KINKED
OR OTHERWISE DAMAGED, IT SHOULD BE REPLACED.
CHECK FOR DAMAGE NEXT TO THE METAL ENDS OF
THE HOSE.

COPYRIGHT 2007 AVON - ISI 7
2.3.3 AirSwitch: Open control slide on AirSwitch by
pressing inward and upward on two protruding tabs
on both sides of control slide. Also make sure the
red bypass knob is in the closed position (i.e. fully
turned clockwise when looking at front of mask). See
paragraph 3.1.9 for connection instructions.
RDV: Push inward on the RDV First Breath Button.
Also, make sure the red bypass knob is in the closed
position.
2.3.4 Ensure high pressure handwheel is tightened com-
pletely prior to opening the cylinder valve. Open the
cylinder valve slowly by turning the cylinder valve
knob counterclockwise to the fully open position.
The console should emit an audible chirp. The bell
should activate and then shut off. There should be
no air flow from the facemask. If air is flowing, check
that the bypass valve is closed.
WARNING
ENSURE THAT ONLY A 2216 PSI CYLINDER IS USED
WITH LOW PRESSURE PNEUMATICS AND A 4500 PSI
CYLINDER IS USED WITH HIGH PRESSURE PNEUMAT-
ICS.
2.3.5 CHECK CYLINDER PRESSURE: The heads-up dis-
play will have four lights "on" when the cylinder is
full. When the cylinder pressure is between 3/4 and
7/8, the top green light will be flashing and the ana-
log pressure gauge readout should read at or above
the 7/8th level. If the top green light is "off" or below
the specified levels, refill the cylinder or replace with
a fully charged cylinder.
2.3.6 AirSwitch: While holding the facemask, push down
on the top of the control slide to close the AirSwitch
and QUICKLY push back to the UP position. There
should be a rush of air when the slide is pushed
down, and the air flow should stop when the slide is
in the UP position.
RDV: RDV can be attached from either left or right
orientation. Dock RDV into facemask by turning the
RDV until the bypass knob is facing either the 1
o'clock or 4 o'clock position depending on user com-
fort. Place RDV into mask and rotate till latch is in
the 12 o'clock position (1/8th turn to lock). Inhale to
active airflow. Attempt to rotate RDV to ensure RDV
is locked.

WARNING
IF ANY OF THE PREVIOUS TESTS FAIL, REMOVE APPA-
RATUS FROM SERVICE, TAG, AND RETURN FOR REPAIR
BY AVON-ISI AUTHORIZED PERSONNEL.
TECHNICIAN MAINTENANCE
AT LEAST ONCE PER YEAR, THE ENTIRE SCBA SHOULD
BE PLACED OUT OF SERVICE AND TAGGED FOR ANNU-
AL FLOW TESTING BY AN AVON-ISI AUTHORIZED
TRAINED TECHNICIAN.
2.4 SCBA RETIREMENT
Over the course of time, the Viking SCBA needs to be evalu-
ated on its' overall condition. Inspect the Viking's harness as-
sembly for frayed, deteriorating harness', stress cracks in the
backframe and in general, it's overall condition. Another con-
sideration is passing the annual dynamic flow testing require-
ments. Over time components may need to be replaced or
consideration must be made to retire the SCBA.
Fire Department that plans on retiring their SCBA's or no
longer meet the current NFPA requirements, should review
NFPA 1852, 2002 Edition, section 4.3 and 4.6 for guidelines
on retiring an SCBA.
3.1 DONNING PROCEDURES
3.1.1 Position the VIKING SCBA on the ground with the
cylinder valve facing away from the wearer.
3.1.2 Spread the shoulder straps and fold open the side
arms. Ensure all strap assemblies (side and waist)
are fully extended and waist belt buckle assembly is
not connected. Reach inside the harness assembly
and grasp the frame with both hands.
3.1.3 Swing the unit up and over the head, making sure
that the elbows extend through the loops formed by
the shoulder straps. Allow the unit to slide down the
back.
3.1.4 Pull directly down on the shoulder straps to adjust
position of unit on back, attach chest strap.
3.1.5 Connect the waistbelt buckle and adjust waistbelt to
a comfortable snug fit by pulling simultaneously on
both left and right adjustment straps. Tuck the ex-
cess waistbelt and shoulder strap pull-downs inside
the waistbelt.
2.3.10 PASS: If equipped, open cylinder to pressurize the
pneumatics console and PASS alarm should chirp
twice to indicate both devices are active. Allow
PASS to go into pre-alarm and full alarm. Reset
PASS. Inspect console for cracks and abrasion, ob-
serve low battery indicators on front cover of con-
sole. Inspect front speaker cover for cracks. Refer to
section 9.0 for console function buttons. If any part
of console is damaged, tag the unit our of service.
2.3.11 LOW PRESSURE ALARM TEST: Gradually reduce
the system pressure by slightly opening the bypass
valve. Verify that the bell sounds and the mask dis-
play blinks a single red LED as the needle from the
analog gauge is at the 1/4th increment.

3.1.8 To connect the facemask to the Viking unit, connect
electronics plug partially into socket, then connect
facemask plug into connector. Press firmly in to lock
both fittings into each socket. A click should be
heard when it is locked in place securely.
NOTE: When connecting the facemask hose to the connec-
tor, make sure both hoses are connected and the
socket sleeve has moved forward. If socket sleeve
has moved forward without the facemask hose con-
nected, air will leak out of the socket connector.
For the RDV mask, the HUD electronic connection
is made when the RDV is docked into the facemask.
Prior to donning the RDV, ensure that the contact
pins are free of any debris.
NOTE: In an IDLH atmosphere, such as a CBRN response,
ensure that the facemask is connected to the pneu-
matic connection prior to entering the hazardous
area to prevent contamination.
NOTE: Prior to docking the RDV, the user can perform a
negative pressure check on the AVON-ISI mask.
Place your hand to block off the RDV opening in the
facemask. Inhale slightly and hold your breath.
Facemask should move inward slightly and stay in
that position unit user exhales. It may be difficult to
perform this with a gloved hand. Annual fit testing is
required to ensure proper fit. Two LED on console
will be green
NOTE: It is not necessary to perform a negative pressure
check on the AirSwitch because it is designed as a
positive pressure facemask. AVON-ISI recommends
annual fit testing to ensure a proper fitting facemask.
AVON-ISI offers facemasks in three different sizes to
ensure a proper fit. Refer to the AVON-ISI Instruction
Sheet for the Viking Facemask (p/n 084022, a/w
A49022) for proper sizing of the facemask.

der valve open, push down on the control slide to ac-
tivate air supply and breathe normally.
RDV positive pressure fit check: With the mask
donned and the RDV docked, inhale to activate air-
flow.
Insert two fingers between the facemask and face.
Gently lift the facemask seal away from the face and
ensure a good outward flow of air, showing that the
facemask pressure is positive. Reseal facemask and
stop breathing for 3 seconds. There should be no
sound of air leaking from the regulator, and there
should be no airflow sensed in the eye region of the
mask.
3.2.2 ALARM CHECK: Close the cylinder valve and con-
tinue to breathe normally. As the air reaches the ¼
full level the red LED light should flash rapidly and
all other lights should be out. The secondary bell
alarm should also activate.
3.2.3 Open cylinder valve. Take two to three deep breaths
to ensure you are getting adequate air into the
facemask. The facemask should not move towards
your face.
3.2.4 AIRSWITCH BYPASS CHECK: The red bypass
knob is located in the center of the AirSwitch. Turn
the bypass knob clockwise as viewed inside the
mask (the direction shown by the knob arrow) to
open the bypass valve. A constant flow of air should
pass into the facemask. Turn the knob in the oppo-
site direction to turn the bypass valve off.

IMPORTANT
THE USER SHOULD BE TRAINED ON HOW TO HANDLE A
POSSIBLE EMERGENCY BEFORE ENTERING A HAZARD-
OUS AREA.
The Viking Z Seven SCBA can be equipped with a variety of
fully-integrated solid state features that offer safety and
communication advantages for the user. Review section 9 for
detailed instructions of available options.
4.1 READING THE HEADS-UP DISPLAY (HUD)
4.1.1 The HUD includes five LED lights: two green, two
yellow and one red. Each of the 4 LEDs in a row
represents a quarter increment of the rated service
pressure. As cylinder pressure decreases, the LEDs
change status. At full rated service pressure, all four
LEDs are on. As cylinder pressure drops below full,
the top green LED begins blinking. At ¾ rated service
pressure, the top green LED turns off and the next
green LED begins blinking. At ½ rated service
pressure, the second green LED turns off and the
yellow LED begins blinking. At ¼ rated service
pressure, the yellow LED turns off, and the red LED
blinks at a fast rate. The top offset yellow light is a low
battery indicator. Refer to the following table for more
information regarding mask pressure display interpre-
tation.
3.2.5 RECHECK CYLINDER PRESSURE: Check the
heads-up display. Four lights should be "on". The
top green light may be flashing, indicating at least
7/8th full. Verify the analog gauge is at or above the
7/8th level.
3.2.6 BATTERY CHECK: The top yellow LED will be "ON"
when the control console batteries are low. If the
pass batteries are low, displays red LED on console
and the pass alarm will chirp every 15 seconds. The
LED on the console will be red. If the SCBA shows a
low battery warning, replace batteries in accordance
with section 8.3.
3.2.7 VAS CHECK
3.2.7.1 Turn SCBA on by either opening cylinder valve or by
manually depressing on buttons.
3.2.7.2 Hold mask up to face and speak into mask.
3.2.7.3 Listen to speech emanating from VAS speaker and
ensure its intelligibility and function.

4.2.2 The
end-of-service-time
alarms (mask display and
bell) activate when there is approximately 25% of the
full air supply remaining. Egress when alarms
activate. WARNING: 25% OF A FULL CYLINDER
MAY BE INSUFFICIENT IN SOME CIRCUM-
STANCES TO SAFELY EXIT FROM AN IDLH
ATMOSPHERE. One example would be a long-
distance ingress through a continuous IDLH atmo-
sphere. In such situations, begin egress prior to
activation of the
end-of-service-time
indicator.
4.3 CBRN SPECIFIC ACTIONS
Hazardous materials, such as CBRN agents, may
not present immediate effects from exposure, but can
result in delayed impairment, illness, or death.

4.7 RIC FITTING PROCEDURES
The RIC fitting is designed as an emergency refill only and
has specific uses and functions per NFPA 1981, 2007
Edition. The system can only be used to fill approved SCBA
cylinders. The RIC fitting has an internal balanced piston
that prevents over pressurization of a cylinder. A check valve
prevents fire fighters from transfilling SCBA’s, or any other
unapproved use on AVON-ISI products. Users will be able to
have a 4500 psi cylinder as a supplied air system and
connect to a 2216 psi SCBA RIC connector. Air will stop
flowing automatically from the high-pressure cylinder when
the correct pressure (2216 or 4500) is achieved.
To recharge a cylinder on a downed fire fighter, an approved
charging hose must be used. The AVON-ISI Rescuer uses
the following approved hoses: a 3 foot RIC Charging Hose
(p/n 162051), a 6 foot RIC Charging Hose (p/n 162052), or a
10 foot RIC Charging Hose (p/n 162053) for filling the
cylinder in IDLH atmospheres.
4.7.1 Open cylinder valve of supplied air and remove the
dust cap from the RIC charging hose. Inspect the
fire fighters cylinder for damage and ensure that the
cylinder valve is fully opened.
WARNING
CYLINDERS THAT ARE DAMAGED MAY SUDDENLY
RUPTURE IF CHARGED.
4.7.2 Remove dust cap from the RIC fitting on the SCBA
and attach the RIC charging hose to it. Listen for
leaks on the SCBA that is being filled. Recharging
will take between 2-4 minutes, depending on the
cylinder duration and pressure. When the pressures
equalize, unplug the charging hose from the SCBA
and replace dust covers and exit. During a
prolonged rescue, users can leave the supplied air
cylinder plugged into the downed fire fighter’s
SCBA, adding additional duration to the cylinder.
NOTE: If any time during charging, a leak is detected;
discontinue charging and exit IDLH atmosphere
immediately.
NOTE: In a non-emergency situation, cylinders shall not be
refilled through the RIC.
4.7.3 Once clear of an IDLH atmosphere, close the cylinder
valve on the RIC charging hose. Ensure there is no
debris in the dust cap prior to pushing on the dust
cap. The bottom of the dust cap reads "press to
relieve". With dust cap in place, push down on dust
cap on a hard surface to bleed pressure.
4.7.4 Top off cylinder attached to charging hose before next
use to ensure proper service time.
IMPORTANT
DO NOT REMOVE ANY EQUIPMENT UNTIL YOU ARE
CLEAR OF AN IDLH ATMOSPHERE.
4.8 PASS
The wireless network between the PASS and control console
must always be updating. You must verify on start-up that the
console's LEDs are green. If console LED flashes red for more
than 30 seconds, the PASS will go into alarm and will not turn
off until backframe batteries are removed. Usually the cause is
low battery from either power source that never was changed.

every 12 seconds and the console LED pass light will
be red.
NOTE: Electronics will operate at least two hours in low
battery mode.
Battery life depends on many variables. Some fire
departments may use the Viking once every day for
six months before they have to change batteries.
Another fire department may only use the Viking
once a month. Both batteries may have to be
replaced within six months. The difference is the
amount of power loss from using the electronic
options. The Viking Z SEVEN has several options
that can increase battery consumption. The VAS
draws about 700 ma. and radio communications
draws about 250 ma. The rest of the lights that use
LED’s draw very little power. Heat and cold also
affect battery life. During internal heat tests (160 ºF)
and cold tests (-25º F) battery life dropped by 50%.
WARNING

9.1.2 COMMUNICATIONS
The Viking Z SEVEN is available with several communication
options. The microphone is a standard feature and is mounted
inside the facemask on the nosecup. It offers excellent speech
clarity. All communications have a noise suppressor to reduce
exhaled breathing air noise.
Note: The Viking Z SEVEN electronics and pneumatics
turn on automatically when the cylinder valve is
opened. The SCBA electronics can be turned on
manually by depressing the lower two ON/OFF but-
tons on the console.
9.1.2.1 VOICE AMPLIFICATION SYSTEM (VAS)
The VAS uses a sealed, in-mask microphone to
capture the user's voice, amplifies it, and then
broadcasts it from the speaker on the console. This
is particularly useful in communicating with other
people nearby when the SCBA is in the positive
pressure mode. VAS is preset to be voice acti-
vated. You must speak slightly louder than normal
to activate VAS.
The VAS is on standby mode whenever the SCBA
cylinder is opened. When speech is sensed, it turns
on the amplifier and sends it to the console. Shortly
after speech ends, the amplifier goes back into
standby mode.
VAS can be turned off if the user desires. To turn
off the VAS, the cylinder valve must be opened and
power activated to the control console. To disable
the VAS, push inward on the Function key and
push the PTT button. An audible chirp should be
heard. VAS is now in the off setting. To turn VAS
back on, repeat the above function. When the Vi-
king SCBA is powered down, the system will defaut
to VAS "on" when the electronics are activiated.
9.1.2.2 VOICE ACTIVATION LEVELS
The microphone activation level is adjustable for in-
dividual preference. Push the Shift button on the
front of the console inward and hold. The HUD
facemask display will flash the preset point of the
voice activation level. To change the settings, while
holding the Shift key, push the PTT button once.
This will raise the activation point. Continue to push
the PTT to your personal preference. Release the
Shift key to set activation level. To go from Level 4
to Level 1, hold the Shift key inward and push the
PTT button again.
There are ten set points for the voice activation
level. Level 1 is the most sensitive activation point
up to a Level 10 being the least sensitive activation
point. Each level will be displayed a specific num-
ber of HUD light(s) that activate. With each in-
creased level, less inhalation breathing noise is
heard, but voice must be raised higher to begin am-
plification in order for the microphone to detect
speach. The settings are a follows:
Level HUD LED Pattern
1 Flashing Red
2 Red, Flashing Yellow
3 Red, Yellow, Flashing Green
4 Red, Yellow, Green, Flashing Green
5 Red, Yellow, Green, Green

9 Red, Yellow, Green, Flashing Green, Low Bat
10 Red, Yellow, Green, Green, Low Bat
1 2 3 4 5 6 7 8 9 10
9.1.2.3 RADIO INTERFACE
When the Z SEVEN is equipped with radio interface, it
has the ability to significantly decrease the background
noise of outgoing transmissions. This is due to the
placement of the sealed microphone inside the
nosecup, which is well insulated from ambient noise. In-
coming transmissions are broadcast from the console
speaker. On units designed for use by law enforcement,
incoming transmissions are recieved through an op-
tional ear speaker.
A separate radio lead is required to integrate the con-
sole to the radio. The radio connects to the interface
cable on the lower control console.
.
There are two ways to key the radio and transmit: in the
manual mode, press and hold the Push-To-Talk button
(PTT) on the side of the console. As an indication that
the PTT button has been pressed, the right LED indica-
tor light turns green on in the console display and a
solid green light on the HUD. If VAS is installed with
Radio Interface, the VAS is disabled whenever the radio
is keyed.
To activate the hands free VOX mode, press and re-
lease the PTT button twice within one second (double
click). A flashing red light will illuminate on the control
console display. In this mode, the radio is keyed auto-
matically whenever the SCBA senses user speech. The
HUD will illuminate only the top green (full) light when-
ever user speech has keyed the radio. When speech
has ended, the unit automatically turns off the amplifier
to conserve the battery and the HUD again monitors
cylinder pressure. To end the hands free mode, double
click the PTT button again.
9.1.3 Viking Z SEVEN PASS
The PASS on the Viking Z Seven is an NFPA 1982
compliant Personal Alert Safety System (PASS) that
is integrated with the SCBA and with the other
Amount breathing

20
electronic systems. It requires no adjustments.
The PASS is automatically activated when the
cylinder is opened or may be manually turned on by
pushing both "ON/OFF" side buttons on the console
simultaneously. Once turned on, it normally operates
in the “sensing” mode where it looks for motion at the
console.
9.1.3.1 PASS Operating Instructions
WARNING
ALWAYS TEST THE PASS PRIOR TO ENTRY INTO
A HAZARDOUS ATMOSPHERE. IF THE LOW
BATTERY WARNING SIGNAL ACTIVATES,
INSTALL NEW BATTERIES AFTER USE OR PRIOR
TO USING THE VIKING Z SEVEN. THE CONTROL
CONSOLE WITH PASS SHOULD BE POSITIONED
FLAT AGAINST THE SHOULDER STRAP.
When the PASS is turned on, a chirp will be heard on
the control console speaker, followed by a chirp from
the PASS alarm on the backpack. Additionally, the left
LED users prospective on the console display will
slowly flash green when PASS is on. When there is a
lack of motion sensed at the control console for over
25 seconds, the PASS will go into pre-alarm and
sound an audible warning that will progressively get
louder until the PASS goes into full alarm. While in
pre-alarm, the red (¼ full) and top green (full) lights
on the HUD will flash and the PASS LED light on the
console will change to rapidly flashing red. In pre-
alarm, motion to the control console or pushing the
side buttons on the console will return the PASS to
the sensing mode.
If no motion is sensed for a full 35 seconds (including
the pre-alarm warning), the PASS will go into full
alarm and can only be reset by pushing in on the two
side ON/OFF buttons on the console.
9.1.3.2 PASS Safety Certification and Approval

9.1.3.4 PASS Limitations
The VIKING Z SEVEN is designed to meet the design
and performance requirements for Personal Alert
Safety Systems (PASS) to be used by firefighters
engaged in rescue, fire fighting, and other hazardous
duties defined in the NFPA 1982 Standard on PASS,
2007 edition. Failure to ensure that the Viking Z
SEVEN PASS is fully operational prior to use may
expose the user to serious injury or death. Although
the Viking Z SEVEN PASS meets the current
standards, there is no guarantee against PASS
failure. Most performance properties of the PASS
cannot be tested by users in the field.
9.1.3.5 PASS Warranty
AVON-ISI warrants the Viking Z SEVEN PASS to be
free from defects in workmanship and materials for a
period of one year from date of purchase. AVON-ISI
will not repair or replace any merchandise that has

AVON-ISI Customer Service at (888) 474-7233. After
working with the manufacturer to resolve any issues,
they may be reported to SEI at (703) 442-5732.
9.2 VIKING STEALTH MODE
The Viking Z-ST model designed for law enforcement has the
capability of turning off the control console. The Stealth Mode
is a standard feature of the Viking Z-ST.
On units with the stealth mode option, depress the funtion
key and the PPT button on the control console for one sec-
ond to turn off VAS. The HUD will still display cylinder pres-
sure and acknowledge radio transmissions. All communica-
tions will be received through the optional ear piece interface
cable. To reset to normal mode, depress the function key and
PTT button on the control console for one second.

LIMITATIONS & OPERATION
NOTE: The EAS option is available on all models of the
Viking SCBA.
9.3.2.1 The EAS tether is designed so you do not have to
unplug the regulator hose from the facemask in an
IDLH atmosphere. The EAS tether includes two feet
of retractable hose stored within the backframe. The
end of the hose includes two couplings, one male and
one female, and a combination handle/dust cap.
When stored, the EAS handle is located on the lower
right side of the backframe (from the user’s perspec-
tive). In an emergency, the EAS tether is pulled out of
the backframe and connected to another EAS tether
forming a four foot long combined tether hose.
9.3.2.2 If the EAS is used, egress immediately to a safe,
respirable atmosphere. The rescuer must monitor
their cylinder air closely due to increased air con-
sumption.
9.3.2.3 Although the EAS is a NIOSH accepted SCBA
accessory, NIOSH does not approve the use of EAS
devices. Use of the EAS voids NIOSH approvals
while in use.
9.3.2.4 REMOVE THE EAS TETHER: Using your right hand,
reach back above the cylinder valve knob and locate
the buddy breather handle. Pull down on the handle
and completely pull out the hose. The tether is
approximately two feet long.
9.3.2.5 CONNECT TO ANOTHER EAS TETHER: Each EAS
tether includes both male and female quick connect
couplings. Connect one coupling, either male or
female, to the opposite coupling on the other EAS
